Arlington | 3/4" Knockout SNAP2IT® MC Connectors

NEW from Arlington

SNAP2IT® MC Cable Connectors for 3/4” KO

Snap Assembly into Box (No Tools!) or Install with Locknut

Arlington’s one-piece SNAP2IT® fittings for 3/4" knockouts save time with easy snap-in installation. To SNAP the assembly into the box, use the 387AST or 407AST fitting. If you prefer a LOCKNUT for installing the assembly into the box, use the 387A or 407A. The red tinting in the 407A and 407AST indicates our "open tang" design, meaning there is more room inside the fitting for easy insertion of wires.
